In the first stage, we developed stressed-skin wooden panels. Stressed-skin semi-monocock structures are often used for the light structures such as aircraft airframe components. In these structures, the stresses are carried not only by the framing members but also by the surface membrane. There has recently been increasing use of moment resisting glulam timber joints in building structures. However, these joints require relatively large cross-sections because the moment resistance is carried by only the linear elements. This is not only uneconomical but also unattractive. Bending experiments on panel joints were carried out. We have proposed moment resisting timber joints using stressed-skin effect. It has also presented equations for estimating the rotational rigidity and the maximum strength of the joints, and demonstrated their prediction capability with sufficient accuracy. It has been shown that a frame with a smaller cross-section than that of only rib members is achievable with this joint.In the second stage, we developed steel plate and sugi glulam timber structural members. Massive amount of Japanese cedar trees planted in Japan in 1950's are recently ready to be cut for usage, and various techniques utilizing such domestic cedar are required. However, for cedar timber has less stiffness and strength than Douglas fir, combination with steel to provide composite members will be one of the effective methods to expand the structural variations. Thin steel plate is sandwiched between two cedar glulams using shear-ring connectors and bolts. This study is aimed at developing this compoiste member.Axial compression tests and bending tests were conducted to determine the compression and bending characteristics.We proposed equations for estimating the strength and buckling mode, and demonstrated their prediction capability with sufficient accuracy.

在第一阶段，我们开发了应力皮木板。受力蒙皮半单体结构常用于飞机机身部件等轻型结构。在这些结构中，应力不仅由框架构件承受，而且由表面膜承受。最近，在建筑结构中越来越多地使用抗弯胶合木接缝。然而，这些接头需要相对较大的横截面，因为力矩阻力仅由线性元件承载。这不仅不经济而且没有吸引力。对面板接头进行了弯曲实验。我们提出了利用应力集肤效应来抵抗力矩的木节点。它还提出了估计关节旋转刚度和最大强度的方程，并证明了它们具有足够精度的预测能力。事实证明，通过这种接头可以实现横截面比仅肋构件更小的框架。在第二阶段，我们开发了钢板和杉木胶合木结构构件。 1950年代在日本种植的大量日本柳杉最近准备被砍伐以供使用，并且需要各种利用这种国产柳杉的技术。然而，由于雪松木材的刚度和强度均低于花旗松，与钢材组合提供复合构件将是扩大结构变化的有效方法之一。使用剪环连接器和螺栓将薄钢板夹在两块雪松胶合木之间。本研究旨在开发这种复合材料构件。进行了轴向压缩试验和弯曲试验以确定压缩和弯曲特性。我们提出了估计强度和屈曲模式的方程，并证明了它们具有足够精度的预测能力。
